CONTAINER AND PARTS THEREFOR Philip Zalkind, New York, Y.

original'application October 19,1935, Serial No. I v 45,715. Divided and this application September 29, 1939, Serial N0. 297,031 1 ,2 Claims. (01. 45-47) My invention is a true division of application Serial No. 45,715, filed October 19, 1935, Patent No, 2,200,319, and relates to collapsibleand/or folding containers; and more' particularly to novel construction of drawers and the like of this class and novel construction of the parts with which said drawers and the like coact to facilitate movement of said drawer relative to said coacting parts.

In the movement of the drawers in and out of the container in which the drawer is adapted to operate, it is desirable that as much freedom of movement as possible shall be obtained. The patent application of which this is a division was a continuation in part of my copending applica tion Serial No. 693,841, filed October 16, 1933. Patent No. 2,233,906, in which I have shown novel construction for facilitating the movement of a drawer in a collapsible casing, and of my copending application Serial No. 739,962 filed August 15, 1934, Patent No. 2,159,069, in which I have shown novel construction for facilitating the movement of a drawer in a folding or collapsible cabinet.

In the aforesaid applications, I have shown a substantially flat bottom drawer offibrous sheet material with novel wheel and track construc-' tion. This construction isgenerally very efficacious in reducing the friction between the drawer and the container, but I have found that with certain drawer loadings, the drawer bottom will sag or bow an amount to permit the drawer bottom to make contact with the bottom of the casing unless the wheels and tracks or rails are so mounted as to hold the drawer some distance above the bottom of the subjacent part. If the drawer bottom should sag under loading asufiicient amount to come into contact with the subjacent part, the full benefit of my anti-friction mounting cannot be obtained. 1 I

I have found that where it is expected to load the drawer in such a manner that, without a special construction, the drawer would rub on the subjacent part when loaded, I mayz provide means in the construction to eliminate such action.

Moreover, I have found that I may combine various parts of the anti-friction member with reinforcing or connecting members and thus obtain an economy of construction through such combination of parts. I have also found that other economies of construction may be attained through certain novel rearrangement of parts which expedite the manufacture of my novel construction.

Accordingly, objects of my invention are to provide novel apparatus, for and methods ofmoving drawer's into and from its container On wheels or rollers; novel apparatus for and methods of mounting collapsible drawers to be moved on wheels or rollers from and intoa collapsible container; tracks secured to the container and/or to the drawer and rollers or wheels cooperating with said tracks for providing a maximum freedom of movement of the drawer with respect to its containerynovel drawer construction to reduce sagging of the drawer bottom upon the subjacent part; tracks combined with reinforcing and/or connecting members; improved construction :as affecting manufacture. 7 There are other objects of my invention which together with the foregoing will appeari'n the detailed description following in connection with the drawing in which: ii Figure 1 is a perspective view of a form of bottom pad which'may be used in a collapsible container.

Figure 2 is a perspective view, partly broken away, showing the pad'of Figure 1 secure d' in place within a casing. 1

Figures 3 to 5 are perspective views of modified forms of bottom pads with modified forms of tracks.

' Figure 6 is a perspective view of a further'modified form of bottom pad, particularly adapted for use witha three side casing. j

Figure '7 is a perspective view of a further modified form of bottom pad, particularly adapted to a roller form of drawer support;

Figure 8 shows a-form of ball roller members for use with bottom pad of Figure '7.

Figure 9 is a cross-sectionalviewshowing the manner in which'a ball is rotatably'secured in the member of Figure 8. I v

Figure 10 is a view in perspective corresponding to that of Figure 2 showing the 'pad of Figure 7 in place ina casing.

In Figure .1, I have shown a pad 10' having the bottom panel I' andthe side extensions" which may be bent at right angles to the bottom member along the score lines 13, The pad is of course designed for use in a collapsible container, on the bottom wall thereof. The side extensions are provided with the trackmembers 14 having the tracks 15. These members 14 are attached to the side extensions 12 by any suitable means, as forin'stance jthe prongs 16 formed from the members themselves. These prongs may be forced through'the ide extensions 12 and clinched to same as shown at 11." The track members I4 may be provided with the channel shaped top member I8 adapted to finish off the edge of the side wall extensions as shown, or the track member may terminate substantially at the top of the side wall extensions, omitting the channel shaped trim I8.

The pad I8 may be adhesively applied to the.

bottom of the casing or it may be attached thereto by other means. As shown in Figure 1, the pad bottom has a bottom extension I9 at the rear end, and both the bottom and side extensions protrude forward. at 88 beyond track members I4.

As shown in Figure 2, the bottom pad of Figure "I, hereinafter described, may be used with a casing I6 such as has been described. in my patents and applications previously referred to. The pad is inserted into the bottom of the casing preferably after the casing has been set up in rectangular cross section, before the front vertical reinforcing members 24 have been bent back on their bending lines. 7 I

The casing with. the pad as shown in Figure 2 may be used with a drawer of. the type described my aforementioned patents and applications.

Figure 3- shows another modified pad BI with the rails attached thereto by the extended lugs 83 passing through slots in the pad and lugs 84 clinched around the edge of the pad.

In Figure 4, the pad 85 has the bottom panel 86 and the side extensions B'I, which may be bent from the blank along the score lines 88. The side extensions are provided with the rail members 89 similar to the members M of Figure 1, and the bottom 86 has the rails 98 similar to the rails" 82 of Figure 3;

In Figure 5, I have shown a modified form of track member 9t, applied to the side extensions 92 of the pad. Track members BI have the upper rail 94' and the lower rail 95' adapted to coact with a. wheel on a drawer member, the wheel being positioned between the rails 94 and 95 and contacting either one or the other of the two rails Thus when used with a wheel positioned on the rear end of the drawer,,and having tracks hung over wheels on the front:verticafreinforcing members, the upper rail 94 will coact withthe wheel when the drawer is out from the casing and the lower rail 95 will coact with the wheel when the drawer is some distance in the casing. The

drawer will thus be held in substantially level position by the two rails 94: and 95 coacting with the drawer wheel, and will be entirely supported by anti-friction members at all positions within the casing.

The pads shown in Figures 1,4 and. comprise two side wall members connected by a bottom member. In some instances these members may 1 be used separately. Thus in Figure 3, I have shown a bottom pad without side wall extensions, said bottom pad being of similar construction to the bottom connecting members 86. of Figure 4. In a similar manner, side wall members may be used without the bottom member. Thus the side wall member I2 with track member [4 attached as shown in Figure 1,. may be used by itself and secured to the side wall of a casing, or cabinet. by any suitable means. Similarly side wall member ill of Figure 4 with track member 98 may be used in alike manner, as well as sidewall members 92 with track member SI of Figure 5.. Similarly the track members may have a various relative placing on the pad members; and, as is obvious the various parts: shown insaid Figures. 1 and 5 may be arranged reference to, each. other that faced track 98, the bottom of the balls thus rest ,ing channel portions II5.

they may be applied or installed in an inverted Position.

In Figure 7 I have shown a pad 96 which is also shown at the base of the casing of Figure 2 having the rails 98 adapted to support the roll train 99 shown in Figures 8 and 9. As shown the rails are a portion of the metal sheet 91 which is held onto the pad by the flanges I88. However, any other suitable means may be used for attaching the rails to the pad.

Each of the rails 98 may be provided with a roll train 99 which should be approximately one-half of the length of'the rail. As shown in the figures, the roll train is provided with the flanges IN and I82 whichex'tend respectively over the side walls I83 and I84 of the rail member and hold the roll train in place on the rail. Each roll train is punched out in a number of locations as I 85 which are provided with upper prongs I86 and lower prongs I81 between which the ball I88 is loosely held in a manner that the top of the balls project some distances above the top of the upper prongs and thebottom of the balls project some distance below the bottom of the lower prongs. When the roll train is placed upon the hard surupon the track and the roll train is free to move longitudinally off the track with the balls freely rotating in spaced relationship one to the other.

Front stop I 89 and rear stop I I8 may be provided as lugs bent up from the metal of the rail. These lugs will contact respectively the front and rear end of the roll train when the roll train is respectively at the front and rear end of the track, and will thus prevent the roll train from running off of either end of the track. In the use of this form of drawer support, the drawer is simply inserted into the casing and is supported on the balls upon which the drawer will move with true rolling motion when pulled back and forth in the casing. It is essential that the bottom of the drawer have a strip of hard material where it rests upon the balls toprevent the balls from sinking into the material of the drawer; and I prefer that a drawer having metal clad bottom flanges be used with the metal clad flangesbearing upon the ball roller members.

In Figure 10 I have shown the manner in which the pad of Figure '7 may be placed in a casing;

In Figure 6, I have shown a further modified form of pad as a means of supporting the casing rails. In this figure pad III has the downward turned flanges I I 2 to which are attached the rail members I I3 having the rails I I 4 and the depend- This form of pad is especially adapted for use with a three sided casing having two side panels and a top panel. The bottom edges of the side walls of the three sided casing may be held within the flanges I'I5 of the pad III which thus forms a bottom panel for the casing.

Having described my invention, I prefer to be limited not by the specific disclosure but only by the appended claims.

I claim:

1. In a collapsible container, a bottom wall, a pad insertable into said container and disposable on said bottom wall and tracks on said pad', said tracks having a U-shaped section, free rollers in said tracks and means guiding said rollers within said tracks, said last mentioned means comprising a channel member mountable over said tracks and having perforations wherein said free rollers are rotatably captured.

2. In a collapsible container, a bottom wall, a pad insertable into said container and disposable on said bottom wall and tracks on said pad, said tracks having a U-Shaped section, free rollers in said tracks and means guiding said rollers within said tracks, said last mentioned means comprising a channel member mountable over said tracks and having perforations wherein .said free rollers are rotatably captured, and prongs surrounding said perforations and en- 'gaging said rollers in registry with the perfora- 5 tions.
